Re: <Start Disk Reorganization> questions

Howdy,

I had not heard of this command on the iSeries and I agree that it has 
questionable value compared to the load balancing that the system does, 
but what the heck, it's saturday so I ran it <vbg>

We have a small 170 with 8gx9 RAIDed where drive 1 is at 27% and all the 
others were at 13.x%, after running STRDSKRGZ drive 1 is still 27%, 
drive 4 is now 5.5% and all others are at 14.6%.

What is going to happen (I think) is that this coming week all new 
activity will be written to drive 5 until it reaches the same 14.6% as 
the others so I have in effect created a disk arm bottle neck!

Oops,
J. Kilgore
